FIELD OF THE DISCLOSURE

Aspects of the present disclosure generally relate to wirelesscommunication and to techniques and apparatuses for uplink controlchannel transmission in high band operation.

BACKGROUND

Wireless communication systems are widely deployed to provide varioustelecommunication services such as telephony, video, data, messaging,and broadcasts. Typical wireless communication systems may employmultiple-access technologies capable of supporting communication withmultiple users by sharing available system resources (e.g., bandwidth,transmit power, or the like). Examples of such multiple-accesstechnologies include code division multiple access (CDMA) systems, timedivision multiple access (TDMA) systems, frequency-division multipleaccess (FDMA) systems, orthogonal frequency-division multiple access(OFDMA) systems, single-carrier frequency-division multiple access(SC-FDMA) systems, time division synchronous code division multipleaccess (TD-SCDMA) systems, and Long Term Evolution (LTE).LTE/LTE-Advanced is a set of enhancements to the Universal MobileTelecommunications System (UMTS) mobile standard promulgated by theThird Generation Partnership Project (3GPP).

A wireless network may include a number of base stations (BSs) that cansupport communication for a number of user equipment (UEs). A UE maycommunicate with a BS via the downlink and uplink “Downlink” (or“forward link”) refers to the communication link from the BS to the UE,and “uplink” (or “reverse link”) refers to the communication link fromthe UE to the BS. As will be described in more detail herein, a BS maybe referred to as a Node B, a gNB, an access point (AP), a radio head, atransmit receive point (TRP), a New Radio (NR) BS, a 5G Node B, or thelike.

The above multiple access technologies have been adopted in varioustelecommunication standards to provide a common protocol that enablesdifferent user equipment to communicate on a municipal, national,regional, and even global level. NR, which may also be referred to as5G, is a set of enhancements to the LTE mobile standard promulgated bythe 3GPP. NR is designed to better support mobile broadband Internetaccess by improving spectral efficiency, lowering costs, improvingservices, making use of new spectrum, and better integrating with otheropen standards using orthogonal frequency division multiplexing (OFDM)with a cyclic prefix (CP) (CP-OFDM) on the downlink (DL), using CP-OFDMand/or SC-FDM (e.g., also known as discrete Fourier transform spreadOFDM (DFT-s-OFDM)) on the uplink (UL), as well as supportingbeamforming, multiple-input multiple-output (MIMO) antenna technology,and carrier aggregation. As the demand for mobile broadband accesscontinues to increase, further improvements in LTE NR, and other radioaccess technologies remain useful.

DETAILED DESCRIPTION

Various aspects of the disclosure are described more fully hereinafterwith reference to the accompanying drawings. This disclosure may,however, be embodied in many different forms and should not be construedas limited to any specific structure or function presented throughoutthis disclosure. Rather, these aspects are provided so that thisdisclosure will be thorough and complete, and will fully convey thescope of the disclosure to those skilled in the art. Based on theteachings herein, one skilled in the art should appreciate that thescope of the disclosure is intended to cover any aspect of thedisclosure disclosed herein, whether implemented independently of orcombined with any other aspect of the disclosure. For example, anapparatus may be implemented or a method may be practiced using anynumber of the aspects set forth herein. In addition, the scope of thedisclosure is intended to cover such an apparatus or method which ispracticed using other structure, functionality, or structure andfunctionality in addition to or other than the various aspects of thedisclosure set forth herein. It should be understood that any aspect ofthe disclosure disclosed herein may be embodied by one or more elementsof a claim.

Several aspects of telecommunication systems will now be presented withreference to various apparatuses and techniques. These apparatuses andtechniques will be described in the following detailed description andillustrated in the accompanying drawings by various blocks, modules,components, circuits, steps, processes, algorithms, or the like(collectively referred to as “elements”). These elements may beimplemented using hardware, software, or combinations thereof. Whethersuch elements are implemented as hardware or software depends upon theparticular application and design constraints imposed on the overallsystem.

It should be noted that while aspects may be described herein usingterminology commonly associated with a 5G or NR radio access technology(RAT), aspects of the present disclosure can be applied to other RATs,such as a 3G RAT, a 4G RAT, and/or a RAT subsequent to 5G (e.g., 6G).

FIG. 1 is a diagram illustrating an example of a wireless network 100,in accordance with the present disclosure. The wireless network 100 maybe or may include elements of a 5G (NR) network and/or an LTE network,among other examples. The wireless network 100 may include a number ofbase stations 110 (shown as BS 110 a, BS 110 b, BS 110 c, and BS 110 d)and other network entities. A base station (BS) is an entity thatcommunicates with user equipment (UEs) and may also be referred to as anNR BS, a Node B, a gNB, a 5G node B (NB), an access point, a transmitreceive point (TRP), or the like. Each BS may provide communicationcoverage for a particular geographic area. In 3GPP, the term “cell” canrefer to a coverage area of a BS and/or a BS subsystem serving thiscoverage area, depending on the context in which the term is used.

A BS may provide communication coverage for a macro cell, a pico cell, afemto cell, and/or another type of cell. A macro cell may cover arelatively large geographic area (e.g., several kilometers in radius)and may allow unrestricted access by UEs with service subscription. Apico cell may cover a relatively small geographic area and may allowunrestricted access by UEs with service subscription. A femto cell maycover a relatively small geographic area (e.g., a home) and may allowrestricted access by UEs having association with the femto cell (e.g.,UEs in a closed subscriber group (CSG)). A BS for a macro cell may bereferred to as a macro BS. A BS for a pico cell may be referred to as apico BS. A BS for a femto cell may be referred to as a femto BS or ahome BS. In the example shown in FIG. 1 , a BS 110 a may be a macro BSfor a macro cell 102 a, a BS 110 b may be a pico BS for a pico cell 102b, and a BS 110 c may be a femto BS for a femto cell 102 c. ABS maysupport one or multiple (e.g., three) cells. The terms “eNB”, “basestation”, “NR BS”, “gNB”, “TRP”, “AP”, “node B”, “5G NB”, and “cell” maybe used interchangeably herein.

In some aspects, a cell may not necessarily be stationary, and thegeographic area of the cell may move according to the location of amobile BS. In some aspects, the BSs may be interconnected to one anotherand/or to one or more other BSs or network nodes (not shown) in thewireless network 100 through various types of backhaul interfaces, suchas a direct physical connection or a virtual network, using any suitabletransport network.

Wireless network 100 may also include relay stations. A relay station isan entity that can receive a transmission of data from an upstreamstation (e.g., a BS or a UE) and send a transmission of the data to adownstream station (e.g., a UE or a BS). A relay station may also be aUE that can relay transmissions for other UEs. In the example shown inFIG. 1 , a relay BS 110 d may communicate with macro BS 110 a and a UE120 d in order to facilitate communication between BS 110 a and UE 120d. A relay BS may also be referred to as a relay station, a relay basestation, a relay, or the like.

Wireless network 100 may be a heterogeneous network that includes BSs ofdifferent types, such as macro BSs, pico BSs, femto BSs, relay BSs, orthe like. These different types of BSs may have different transmit powerlevels, different coverage areas, and different impacts on interferencein wireless network 100. For example, macro BSs may have a high transmitpower level (e.g., 5 to 40 watts) whereas pico BSs, femto BSs, and relayBSs may have lower transmit power levels (e.g., 0.1 to 2 watts).

A network controller 130 may couple to a set of BSs and may providecoordination and control for these BSs. Network controller 130 maycommunicate with the BSs via a backhaul. The BSs may also communicatewith one another, directly or indirectly, via a wireless or wirelinebackhaul.

UEs 120 (e.g., 120 a, 120 b, 120 c) may be dispersed throughout wirelessnetwork 100, and each UE may be stationary or mobile. A UE may also bereferred to as an access terminal, a terminal, a mobile station, asubscriber unit, a station, or the like. A UE may be a cellular phone(e.g., a smart phone), a personal digital assistant (PDA), a wirelessmodern, a wireless communication device, a handheld device, a laptopcomputer, a cordless phone, a wireless local loop (WLL) station, atablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook,a medical device or equipment, biometric sensors/devices, wearabledevices (smart watches, smart clothing, smart glasses, smart wristbands, smart jewelry (e.g., smart ring, smart bracelet)), anentertainment device (e.g., a music or video device, or a satelliteradio), a vehicular component or sensor, smart meters/sensors,industrial manufacturing equipment, a global positioning system device,or any other suitable device that is configured to communicate via awireless or wired medium.

Some UEs may be considered machine-type communication (MTC) or evolvedor enhanced machine-type communication (eMTC) UEs. MTC and eMTC UEsinclude, for example, robots, drones, remote devices, sensors, meters,monitors, and/or location tags, that may communicate with a basestation, another device (e.g., remote device), or some other entity. Awireless node may provide, for example, connectivity for or to a network(e.g., a wide area network such as Internet or a cellular network) via awired or wireless communication link. Some UEs may be consideredInternet-of-Things (IoT) devices, and/or may be implemented as NB-IoT(narrowband interne of things) devices. Some UEs may be considered aCustomer Premises Equipment (CPE). UE 120 may be included inside ahousing that houses components of UE 120, such as processor componentsand/or memory components. In some aspects, the processor components andthe memory components may be coupled together. For example, theprocessor components (e.g., one or more processors) and the memorycomponents (e.g., a memory) may be operatively coupled, communicativelycoupled, electronically coupled, and/or electrically coupled.

In general, any number of wireless networks may be deployed in a givengeographic area. Each wireless network may support a particular RAT andmay operate on one or more frequencies. A RAT may also be referred to asa radio technology, an air interface, or the like. A frequency may alsobe referred to as a carrier, a frequency channel, or the like. Eachfrequency may support a single RAT in a given geographic area in orderto avoid interference between wireless networks of different RATs. Insome cases, NR or 5G RAT networks may be deployed.

In some aspects, two or more UEs 120 (e.g., shown as UE 120 a and UE 120e) may communicate directly using one or more sidelink channels (e.g.,without using a base station 110 as an intermediary to communicate withone another). For example, the UEs 120 may communicate usingpeer-to-peer (P2P) communications, device-to-device (D2D)communications, a vehicle-to-everything (V2X) protocol (e.g., which mayinclude a vehicle-to-vehicle (V2V) protocol or avehicle-to-infrastructure (V2I) protocol), and/or a mesh network. Inthis case, the UE 120 may perform scheduling operations, resourceselection operations, and/or other operations described elsewhere hereinas being performed by the base station 110.

Devices of wireless network 100 may communicate using theelectromagnetic spectrum, which may be subdivided based on frequency orwavelength into various classes, bands, channels, or the like. Forexample, devices of wireless network 100 may communicate using anoperating band having a first frequency range (FR1), which may span from410 MHz to 7.125 GHz, and/or may communicate using an operating bandhaving a second frequency range (FR2), which may span from 24.25 GHz to52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred toas mid-band frequencies. Although a portion of FR1 is greater than 6GHz, FR1 is often referred to as a “sub-6 GHz” band. Similarly, FR2 isoften referred to as a “millimeter wave” band despite being differentfrom the extremely high frequency (EHF) band (30 GHz-300 GHz) which isidentified by the International Telecommunications Union (ITU) as a“millimeter wave” band. Thus, unless specifically stated otherwise, itshould be understood that the term “sub-6 GHz” or the like, if usedherein, may broadly represent frequencies less than 6 GHz, frequencieswithin FR1, and/or mid-band frequencies (e.g., greater than 7.125 GHz).Similarly, unless specifically stated otherwise, it should be understoodthat the term “millimeter wave” or the like, if used herein, may broadlyrepresent frequencies within the EHF band, frequencies within FR2,and/or mid-band frequencies (e.g., less than 24.25 GHz). It iscontemplated that the frequencies included in FR1 and FR2 may bemodified, and techniques described herein are applicable to thosemodified frequency ranges.

As indicated above, FIG. 1 is provided as an example. Other examples maydiffer from what is described with regard to FIG. 1 .

FIG. 2 is a diagram illustrating an example 200 of a base station 110 incommunication with a UE 120 in a wireless network 100, in accordancewith the present disclosure. Base station 110 may be equipped with Tantennas 234 a through 234 t, and UE 120 may be equipped with R antennas252 a through 252 r, where in general T≥1 and R≥1.

Transmitprocessor 220 may also process system information (e.g., for semi-staticresource partitioning information (SRPI)) and control information (e.g.,CQI requests, grants, and/or upper layer signaling) and provide overheadsymbols and control symbols. Transmit processor 220 may also generatereference symbols for reference signals (e.g., a cell-specific referencesignal (CRS) or a demodulation reference signal (DMRS)) andsynchronization signals (e.g., a primary synchronization signal (PSS) ora secondary synchronization signal (SSS)). A transmit (TX)multiple-input multiple-output (MIMO) processor 230 may perform spatialprocessing (e.g., precoding) on the data symbols, the control symbols,the overhead symbols, and/or the reference symbols, if applicable, andmay provide T output symbol streams to T modulators (MODs) 232 a through232 t. Each modulator 232 may process a respective output symbol stream(e.g., for OFDM) to obtain an output sample stream. Each modulator 232may further process (e.g., convert to analog, amplify, filter, andupconvert) the output sample stream to obtain a downlink signal. Tdownlink signals from modulators 232 a through 232 t may be transmittedvia T antennas 234 a through 234 t, respectively.

At UE 120, antennas 252 a through 252 r may receive the downlink signalsfrom base station 110 and/or other base stations and may providereceived signals to demodulators (DEMODs) 254 a through 254 r,respectively. Each demodulator 254 may condition (e.g., filter, amplify,downconvert, and digitize) a received signal to obtain input samples.Each demodulator 254 may further process the input samples (e.g., forOFDM) to obtain received symbols. A MIMO detector 256 may obtainreceived symbols from all R demodulators 254 a through 254 r, performMIMO detection on the received symbols if applicable, and providedetected symbols. A receive processor 258 may process (e.g., demodulateand decode) the detected symbols, provide decoded data for UE 120 to adata sink 260, and provide decoded control information and systeminformation to a controller/processor 280. The term“controller/processor” may refer to one or more controllers, one or moreprocessors, or a combination thereof. A channel processor may determinea reference signal received power (RSRP) parameter, a received signalstrength indicator (RSSI) parameter, a reference signal received quality(RSRQ) parameter, and/or a channel quality indicator (CQI) parameter,among other examples. In some aspects, one or more components of UE 120may be included in a housing.

An antenna panel, an antennagroup, a set of antenna elements, and/or an antenna array may includeone or more antenna elements coupled to one or more transmission and/orreception components, such as one or more components of FIG. 2 .

On the uplink, at UE 120, a transmit processor 264 may receive andprocess data from a data source 262 and control information (e.g., forreports that include RSRP, RSSI, RSRQ, and/or CQI) fromcontroller/processor 280. Transmit processor 264 may also generatereference symbols for one or more reference signals. The symbols fromtransmit processor 264 may be precoded by a TX MIMO processor 266 ifapplicable, further processed by modulators 254 a through 254 r (e.g.,for DFT-s-OFDM or CP-OFDM), and transmitted to base station 110. In someaspects, a modulator and a demodulator (e.g., MOD/DEMOD 254) of the UE120 may be included in a modem of the UE 120. In some aspects, the UE120 includes a transceiver. The transceiver may include any combinationof antenna(s) 252, modulators and/or demodulators 254, MIMO detector256, receive processor 258, transmit processor 264, and/or TX MIMOprocessor 266. The transceiver may be used by a processor (e.g.,controller/processor 280) and memory 282 to perform aspects of any ofthe methods described herein, for example, as described with referenceto FIGS. 3-8 .

At base station 110, the uplink signals from UE 120 and other UEs may bereceived by antennas 234, processed by demodulators 232, detected by aMIMO detector 236 if applicable, and further processed by a receiveprocessor 238 to obtain decoded data and control information sent by UE120. Receive processor 238 may provide the decoded data to a data sink239 and the decoded control information to controller/processor 240.Base station 110 may include communication unit 244 and communicate tonetwork controller 130 via communication unit 244. Base station 110 mayinclude a scheduler 246 to schedule UEs 120 for downlink and/or uplinkcommunications.

As indicated above, FIG. 2 is provided as an example. Other examples maydiffer from what is described with regard to FIG. 2 .

A physical uplink control channel (PUCCH) is a physical channel used bya UE to convey control information. A PUCCH may be generated inaccordance with a format. Different formats of PUCCH may be used tocarry different types of information, may be used in differentscenarios, and may be associated with different characteristics. Abaseline NR deployment (e.g., enhanced mobile broadband (eMBB)) may beassociated with five PUCCH formats (e.g., PUCCH Formats 0, 1, and 4which may occupy one resource block (RB), and PUCCH Formats 2 and 3which may occupy a configurable number of resource blocks).

In unlicensed Frequency Range 1 (FR1) bands, enhanced PUCCH (ePUCCH)formats may be used. The ePUCCH formats may include ePUCCH Formats 0, 1,2, and 3, which are described below. A PUCCH that uses an ePUCCH formatis referred to herein as an ePUCCH. In some aspects, an ePUCCH may usean interlace structure, meaning that RBs of the ePUCCH are interlacedacross a set of resources. The usage of the interlace structure mayincrease the usable power (e.g., to a per UE maximum of 23decibel-milliwatts (dBm)) while conforming with power spectral density(PSD) limits of to 13 dBm per MHz. In some aspects, the interlace mayspread out the RBs of the ePUCCH so that each RB can be transmitted athigher power while remaining under the PSD limits.

In some aspects, for ePUCCH Formats 0 and 1, different RBs in theinterlace may use different cyclic shifts, and a cyclic shift step sizeincrease (e.g., to a step size of may be used for adjacent RBs in theinterlace. In some aspects, for ePUCCH Format 2, frequency-domainorthogonal cover coding (OCC) operations may be performed with OCClengths of 1, 2, or 4 for user multiplexing. In some aspects, the OCCmay be cycled across physical resource blocks (PRBs) of an interface toreduce peak-to-average power ratio (PAPR) and cubic metric (CM) values.In some aspects, for ePUCCH Format 3, user multiplexing of control dataassociated with the ePUCCH may be based at least in part on pre-discreteFourier transform (pre-DFT) OCC with block-wise repetition in the timedomain, followed by mapping over the RBs across the interlace. Usermultiplexing for reference signals may be based at least in part on theuse of different cyclic shifts of the same base sequence for allmultiplexed users. An interlaced set of RBs may be referred to herein asa non-contiguous set of RBs.

A PUCCH in an unlicensed band higher than FR1, such as FR2, may occupy alarger bandwidth than a PUCCH in FR1. In some aspects, with a 120 kHzsubcarrier spacing (SCS), a PUCCH's total occupied bandwidth (referringto eMBB PUCCHs) may be 1.44 MHz for PUCCH Formats 0, 1, and 4, and up toapproximately 23 MHz with PUCCH Formats 2 and 3. As another example,with a 960 kHz SCS, a PUCCH's total occupied bandwidth may beapproximately 12 MHz for PUCCH Formats 0, 1, and 4, and up toapproximately 184 MHz for PUCCH Formats 2 and 3. In higher bands, theremay be a PSD limit of 23 dBm/MHz with up to 40 dBm Effective IsotropicRadiated Power (EIRP). In some aspects, while a mobile terminal (e.g., aUE) may operate at approximately 23 dBm, some other user terminals, suchas CPEs, may operate at a higher EIRP, such as up to the 40 dBm EIRPlimit. However, the wider bandwidth of the PUCCH in the higher bands maymean that interlacing, such as the interlacing prescribed by the ePUCCHformats of unlicensed FR1 causes suboptimal resource utilization.

Some techniques and apparatuses described herein provide ePUCCH formatsusing an increased bandwidth configuration for higher bands, such asFR2, that use a contiguous set of RBs (e.g., without interlacing). Insome aspects, an ePUCCH in a higher band may use a sufficiently widebandwidth that interlacing provides little benefit at the cost ofincreased channel utilization, and the maximum transmit powerrequirements of the higher band may be achievable without usinginterlacing. A configuration for an ePUCCH that uses a contiguous set ofRBs may be referred to as an increased bandwidth configuration.Particular examples of increased bandwidth configurations for anunlicensed higher band are described in connection with FIGS. 3-6 .Thus, resource utilization, efficiency of PUCCH transmissions, and PAPRin unlicensed higher bands, such as FR2, are improved.

FIG. 3 is a diagram illustrating an example 300 of transmitting anePUCCH in a higher band using an increased bandwidth configuration, inaccordance with the present disclosure. As shown example 300 includes aUE 120 and a BS 110. As shown by reference number 310, the UE 120 may beassociated with a higher band, such as FR2 or a band higher than FR2.For example, the UE 120 may be configured to communicate in the higherband. As another example, the UE 120 may be associated with a frequencyhigher than 6 GHz. In some aspects, the UE 120 may be associated with anSCS of 120 kHz, 240 kHz, 960 kHz, 1.92 MHz, 3.84 MHz, and/or the like.Furthermore, the higher band may be unlicensed, meaning that the UE 120may use channel access mechanisms to access the higher band.

As shown by reference number 320, the UE 120 may determine an increasedbandwidth configuration for an ePUCCH based at least in part on anePUCCH format. For example, the UE 120 may receive information (e.g.,configuration information, system information, or the like) indicatingthe ePUCCH format. In some aspects, the information indicating theePUCCH format may indicate a maximum transmission bandwidth N_RB (interms of resource blocks) and the ePUCCH format. In some aspects, the UE120 may use an ePUCCH format based at least in part on the higher bandbeing unlicensed. For example, the UE 120 may determine that anoperating band of the UE 120 is a higher band and is unlicensed and maytherefore determine to use the ePUCCH format. As another example, the UE120 may receive information indicating the ePUCCH format based at leastin part on the higher band being unlicensed.

The increased bandwidth configuration may use a contiguous set of RBsfor the ePUCCH. In some aspects, the increased bandwidth configurationmay not use an interlaced waveform for the ePUCCH. As shown by referencenumber 330, the UE 120 may transmit the ePUCCH in accordance with theePUCCH format. In some aspects, the UE 120 may transmit the ePUCCH usingthe increased bandwidth configuration. In some aspects, the UE 120 mayperform frequency-domain and/or time-domain OCC based at least in parton the ePUCCH format, as described in more detail in connection withFIGS. 4-6 . Thus, the resource efficiency of the ePUCCH may be improved,while a maximum transmit power is achieved.

As indicated above, FIG. 3 is provided as an example. Other examples maydiffer from what is described with respect to FIG. 3 .

FIG. 4 is a diagram illustrating an example 400 of an increasedbandwidth configuration for an ePUCCH Format 0 or Format 1, inaccordance with the present disclosure. The increased bandwidthconfiguration for the ePUCCH Format 0 or 1 may use a contiguous set ofRBs. In some aspects, each RB may span more than 1 MHz, so an interlacedwaveform may not be needed to achieve acceptable transmit power.Furthermore, aggregating the contiguous set of RBs may achieve lowerPAPR than an interlaced waveform. Still further, the usage of contiguousRBs may enable frequency hopping.

In some aspects, the increased bandwidth configuration for the ePUCCHFormat 0 or 1 may use an increased sequence length (that is, an extendedsequence) relative to an existing PUCCH format defined in NR or to anePUCCH Format that does not use an increased bandwidth configuration.For example, a longer sequence with M RBs may be used for ePUCCH Format0 or 1, where M is the number of RBs included in a PUCCH resource. Thus,the sequence may have a length equal to a total number of mapped REs ofthe PUCCH resource. In some aspects, the increased sequence length forthe enhanced PUCCH format 0 or 1 may allow for the increased cyclicshift separation and the increased cyclic shift separation may enablebetter user multiplexing with PUCCH Format 0 or 1. In some aspects,different cyclic shifts may be used to indicate an acknowledgment (ACK),a negative ACK (NACK), a scheduling request (SR), and so on. This may beparticularly beneficial in bands higher than FR1 or FR2, since thechannel's coherent bandwidth can be larger than in FR1 or FR2.Additionally, or alternatively, the increased bandwidth configurationfor the ePUCCH Format 0 or 1 may use a different cyclic shift on each RBspanned by the increased bandwidth and the cyclic shift on each adjacentRB may be increased by a step size with the starting cyclic shiftconfigured or signaled for the first RB for the ePUCCH format 0 or 1 ofa default cyclic shift step size.

In some aspects, the ePUCCH may be split into a plurality of RB groups,such as K RB groups. This is shown by reference number 410. An RB groupmay include one or more RBs. In this case, and as shown, each RB groupmay use a cyclic shift value in accordance with a cyclic shift stepsize. For example, cyclic shifts may be cycled across RBs in accordancewith the cyclic shift step size. In some aspects, a first set of RBgroups (e.g., 12 RB groups, or a different number depending on thecyclic shift and the number of RBs) may use a first root, and a secondset of RB groups may use a second root. In some aspects, the cyclicshift step size may indicate a positive or negative SR. In some aspects,the UE 120 may select a different cyclic shift step size based at leastin part on a positive or negative SR. In some aspects, as shown, theePUCCH may use repetition in the frequency domain. As further shown, theePUCCH may use a sequence of length N for each RB group of the PUCCHresource. In some aspects, N may be equal to the number of mapped REsper RB of the PUCCH resource. In some aspects, the sequence may berepeated in each RB group (such as with a different cyclic shift X₀ . .. X_(k)).

Reference number 420 shows an example of an ePUCCH that uses a longersequence than the example shown by reference number 410. In someaspects, the ePUCCH shown by reference number 420 may use a sequencethat spans a plurality of RBs. For example, the sequence may span theePUCCH (e.g., may have a length equal to the total number of mapped REsof a PUCCH resource of the ePUCCH). In this case, the ePUCCH may use afirst root, and a next ePUCCH may use a second root.

As indicated above, FIG. 4 is provided as an example. Other examples maydiffer from what is described with respect to FIG. 4 .

FIG. 5 is a diagram illustrating an example 500 of an increasedbandwidth configuration for an ePUCCH Format 2, in accordance with thepresent disclosure. In example 500, 2 RBs (each with 12 resourceelements (REs)) are code-division multiplexed (CDM). In some aspects,the increased bandwidth configuration for the ePUCCH Format 2 may usefrequency-domain OCC for a plurality of contiguous RBs. In some aspects,the frequency-domain OCC may have a length greater than 4, such as 6, 8,9, 12, 16, or the like. Here, the frequency-domain OCC has a length of8. Thus, multiple contiguous RBs may be multiplexed with frequencydomain OCC spanning multiple contiguous RBs. This may be particularlyuseful for a 120 kHz SCS, since the channel may be relatively flat insuch an SCS, leading to improved PAPR relative to other SCSs. It shouldbe noted that any number of contiguous RBs can be multiplexed in thisfashion.

As indicated above, FIG. 5 is provided as an example. Other examples maydiffer from what is described with respect to FIG. 5 .

FIG. 6 is a diagram illustrating an example 600 of an increasedbandwidth configuration such as for an ePUCCH Format 3, in accordancewith the present disclosure. The increased bandwidth configuration mayuse block-wise pre-DFT time-domain OCC operations for M contiguous RBs,where M can include all allocated RBs. In some aspects, the OCC lengthmay be extended beyond 4 (e.g., to 6, 8, 9, or another number), whichmay be particularly beneficial for the 120 kHz SCS. In example 600, asshown, block-wise pre-DFT time-domain OCC operations are performed for6M modulation signals [b₀. . . b_(6M−1)] to be transmitted by a UE0(e.g., UE 120) and a UE1 (e.g., UE 120). As further shown, block-wisepre-DFT time-domain OCC operations and DFT spreading leads to the UE0and the UE1 using alternating tones, thus reducing interference betweenthe UE0 and the UE1. For example, the UE0 uses a first tone, a thirdtone, and so on, as indicated by shading of the tones shown by referencenumber 610 in the UF0's diagram. Furthermore, the UE1 uses a secondtone, a fourth tone, and so on, as indicated by shading of the tonesshown by reference number 620 in the UE1's diagram. In some aspects,example 600 may be applicable for an ePUCCH Format 3 or an ePUCCH Format4.

As indicated above, FIG. 6 is provided as an example. Other examples maydiffer from what is described with respect to FIG. 6 .

Exampleprocess 700 is an example where the UE (e.g., UE 120 and/or the like)performs operations associated with uplink control channel transmissionin high band operation.

As shown in FIG. 7 , in some aspects, process 700 may include receivingconfiguration information indicating an enhanced physical uplink controlchannel (ePUCCH) format for an ePUCCH, wherein the ePUCCH is associatedwith an increased bandwidth configuration based at least in part on theePUCCH format of the ePUCCH, wherein the increased bandwidthconfiguration uses a plurality of contiguous RBs for the ePUCCH (block710). In some aspects, the UE (e.g., using controller/processor 280,transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252,and/or the like) may receive configuration information, such as viaradio resource control (RRC) signaling, medium access control (MAC)signaling, downlink control information (DCI), or a combination thereofThe configuration information may indicate an ePUCCH format for anePUCCH.
